Application filed September 12, 1906. Serial No. 334,349.

Province of Ontario, Canada, have invented certain I new and usefulImprovements in fiintiiriction-Bearings; and I hereby declarethat'thefollowing is a full, clear, and exact description of the same.

' This inventionrrelates to an anti-friction hearing comprising one ormore groups of anti- 3 ifrictionbearing members, such as ballsorroliere, maintamed in an annular iormation by peculiarly constructedranged to permit of the individual revolution tans: Fig.

- of the retaining cages looking I end." Fig. 5, is an e same retainingcage, as shown in F19. 4, looin retaining cages aref the anti-frictionbearing members, and prevent their radial and lateral displacementeither individually or collectively.

It further rel'ates to th epeculiar manner of assembling theanti-friction hearinn members one group wiii be opposed to t heintervals between the anti-friction bearing members-0f the adjar centgroup or groups to providea continuous support for the coacting part ata place dia- "lmefirically opposite the application of the .108.

For a fiill understanding of the invention reference is to be'had to thefollowing description and to the accompanying drawings in which, i

Figure 1, is a plan view of an anti-friction hearing showing 1*, is anend elevation of the same. Fig. 2, is a sectional view takencentrally'through the same. Fig. 3, view of one of the retaining cages,shown in the preceding figures with'the anti-friction halis removed.Fig. 4, is an elevation of one at it from the evation of the ing at it"from the closed end, and A 6, a pore ctive view of an anti-frictmnbeanng in which anti-friction rollers are substitute for theanti-friction balls, shown in .the preceding views.

Like'letters of reference refer to like parts throughout thespecification and drawings.

The anti-friction bearing shown in Figs. 1 to 5 inclusive, consists ofthree groups of anti-friction balls a, maintained in their annularformation by annular retaining cages b, Z1 and b respectively. Each ofthe retaining cages consists of an annular cage ring 0 having a centralbore therethrongh, and a series of eq'ui spaced trundles 0? extendingretaining cages, so that t c three groups of anti-friction theanti'hicfion is a plan laterally from one of side faces of the cageringfand slightly lon er than the diameter of the anti-friction bafiiig'lhe planes of the. inner face e andouter face'f of the trundles areconcentric with the axis of of spherical shapes corresponding to thespherical surfaces of the anti-friction halls so that one will offer asubstantialcontact to the oth'er,-and of thei-atter. Y

the cage rings, and their side faces are provide for the free revolutionBy reference to Fig.4, it seen that on the dotted-line h,indicatingthecenters of the anti-friction balls a,'the distance betwee the oppositeside faces 9 of two adjacen trundles is slightly greater than thediameter of the anti-friction ball contained between them, and that thedistance between-the same side faces at the inner and outer surfaces ofthe trundles is iesslthan the diameter of the anti-friction'ball toprovide for the free revolution of the latter between them and toprevent its radial displacement, the

former function being attained by the fact that the curvature of thepocket formed by the side faces of the trundles corresponds to thecurvature of theanti-friction ball, and

the latter by reason of the fact that the- Width of the openings betweenthe side faces of the trundles is less than the diameter of By means ofthis construction, the ball-is retained in a pocket wvhich presents'noobstruction to its free revolution, and yet prevents its displacementradially in either direction so that While it will. be permitted toperform its function of providing an anti-friction bearing for thecoacting member i, it will be prevented from becoming-displacedtherefrom, and will also he prevented from. contacting the adjacent ballon either side of it, which advantage to' the anti-friction be balls.

to the intervals between theanti-friction balls contained in theretaining cages b and b. This construction is effected by providing thecage rings 0 at the opposite-side face to the trundles d with detentsjtoenter the spaces between the trundle's cl of the next adjacent cagering and shaping the side faces of-the detents 7' to correspond with theside faces of the trundies so as to provide not only-for the is ofmaterial" r Q event of damage'; to any of the anti-hiction- HOG l 1 Assho wn in Fig. 1, theanti fi'iction balls 6 contained in the retainingcage 6 are opposed,

. entry entry of the detents into the spaces between the trundles d butalso to provide for the of the trundles (i into the spaces existingbetween the detents, andenable the ends of the trundles'to contact theadjacent surface of the cage ring.

it will be seen by reference to Figs. 2 and 5, that the surface If: ofeach of the detents j which contacts the anti-friction ball, issubstantially cup-shaped and the distance between the cup-shaped surfaceis and the adj acent surface of the cage ring is but slightly greaterthan the diameter of the ball, so that the ball will be permitted tofreely revolve between them, and will be prevented from moving laterallyexcept for an exceedingly limited distance.

In Fig. 6, anti-friction bearing rollers a are. substituted for theanti-friction balls shown in the preceding views. In this case theroller pockets are shaped to correspond with the rollers .hoth asregards their sides and ends, but otherwise the construction of theretaining cages and the arrangement of the parts are the same asdescribed and shown in the preceding figures.

For convenience in fitting the anti-friction bearing on a journal, theretaining cages b, b are divided on the dotted line I which passesthrough two of the detent teeth on either a straight or broken lineradial to the center of the retaining cage.

To assemble the anti-friction balls and retaining cages the latter areplaced so that the cage rings will assume a substantially horizontalplane, and the trundles will assume a substantially vertical plane. Theantieiriction bearing members are then dropped into Having thus fullydescribed my invention the pockets formed by the curved faces of thetrundles.

In placing the co-acting member,

anti-friction bearing on the the sections of the retaining cages areseparated and placed around.

the opposite sides of the eo-acting member 'i and then closed together.groups of the anti-friction bearing members are employed in the bearing,the groups are arrangedas shown in Figs. 1 and 6, and the group orseries of groups are placed in a di vided beefing box m similar to thatshown in the drawings. As the bearing box does not form a material partof the invention and as any style of a bearing box can be employedi'n'combination with the anti-friction bearing, it will not be necessaryto describe it in detail further than to say that the two sections ofthe bearing box m whenbolted together securely maintain the retainingcage sections in their assembled position and prevent their displacementeither radially orlaterallyon the co-acting member.

.placement If one or more seams what i claim as new and desire to secureby Letters Patent is:

1. An anti friction bearing comprisinga retaining cage, consisting of aseries of annular cage rirgs of corresponding diameters, and arranged inparallel planes, and havmg alined annular bores of the same diameter,

trundles projecting laterally from the side faces of the cage rings, andequi-spaced. to form intervening pockets of slightly greater width thanthe diameter of the anti friction bearing elements to be containedbetween them, and having their opposite faces converging to prevent theinward radial disof the anti friction bearing elements, and having thetrundles of one cage ring arranged-opposite the pockets of the nextadjacent cage ring.

2. An anti-friction bearing comprising a retaining cage, consisting ofan annular cage having a central bore therethrough, a sering ri'es oftrundles projecting laterally from one faceof the cage ring and spacedfrom one another by' intervening pockets of reater width than thediameter of the antriction bearing elements which they are to contain,and having their opposite faces curved to correspond with the curvaturethereof, and detents projecting from the other face of the cage ringcorrespondingly shaped to the oppositefaces of the trundles and sepa-.

rated by intervening unoccupied intervals to receive therein thetrundles of the next adjacent retaining cage.

3. An anti-friction bearing comprising a series of retaining cages, eachconsisting of an annul age ringhavinga central bore therethrough, aseries of trundles projecting laterally from one face of each cage ringand equi spaced to form intervening pockets of slightly greater widththan the diameter of the anti-friction bearing elements to be containedbetween them, and having their opposite faces curved vature thereof,detents on the other-face of each cage ring having their facescorrespondingiy shaped to the opposite faces of the trundles, andarranged with unoccupied the trundles and cause the retaining rages to"be assembled so that the anti-friction hearing elements of one groupwill be alined opposite the spaces between the anti-iriction bearingelements of the adjacent group or groups, and anti-friction bearingelements contained in the pockets formed by the annular rings, trundles,and detents.
